Hello from Fort Collins.
My wife and I are looking for just this sort of thing.
I've been hooked on Permaculture since I discovered it about 5 years ago (if fit right in with my ethos and background). I just recently took my PDC this last Spring at Sunrise Ranch in Loveland (birthday gift).
We (wife and 2 young children) currently live in FC and I work at OtterBox, but we have been looking for a little piece of land to start homesteading on and quite ruining this planet.
If we can figure out financing or you are still interested in selling off a smaller portion, maybe we can make something work.
I love the whole like-minded/supportive community/neighbors approach and have been trying to do just that with some friends, but haven't been able to make it work.
Matt
